The Schedule referred to in these Letters Patent and making part f thename.

To all whom it may concern Be it known that I, EGBERT SMITH; of Adamscounty and State of Illinois, have invented a new and improved UniversalCog-W'heel Coupling and Joint, to be used on thrashing and othermachines wanting to-be changed from one direction to another; and Ideclare the following to be a full, clear, and exact description of thesame, reference being bad to the accompanying drawing which make a partof this specification,.and in which- Figure l is a perspective view ormy invention.

Figure 21's a view of the under side or bottom of the platform on whichthecog-wheel coupling stands.

Figure 3 is a vertical sectional view of the platform.

To enable others skilled in theart to make and use my invention, I'willproceed to describe'the manner in which I have carried it'out.

In the said drawing- .A is a platform, on which is rigidly secured thebox B. 4 On the end of the shaft a, having its bearing in the top of thebox B, is secured the oval-faced cog-wheel O, which gears into theoval-faced cog-wheel D, secured upon a shaft, having its bearing in thebox (1.

The box dis secured to the platform A by means or the bolt m, and may bemoved around the platform, the bolt m sliding in the slot F, so as tokeep the cogs of the two wheels 0 and D properly locked or geared.

and thus changing at pleasure the direction of the motion or power.

E'is a lever secured to the bottom of the platform at 13,-(see fig. 2,)so as to 'turn easily upon the bolt t as a pivot, while the opposite endof the lever is left free to move around the circumference of theplatform, and to be secured at any desirable point thereof by means ofthe screw-bolt G, or any other suitable means.

The lever E is slotted at n, and in its passage around the platform, asset forth above, the slot n passes along the line, and immediately underthe slot h in the platform.

- The bolt m which secures the box d,a-nd which slides in the slot F,also'passes through the slot at, and,

by. means of the lever E, is firmly held in position described.
